I ported the loom model checker to C/C++ because I wanted to examine some futex based lock implementations. CDSChecker is another option but it is rather old and less maintained.
Currently, not all "futex" operations are supported. loom4c only provides a limited set of wait/wake operations via wait(expected) and notify_one()/notify_all().
There are Mutex/Condvar/... primitives inside loom. They are not exposed via the C-FFI yet because this project is for now designed for experimenting lock implementations; but porting existing locks can be
easily done.
Some important parts are missing due to the limitation of loom:
- shared memory support
- timed waiting
- weak version of compare_and_exchange
- real
SeqCst(which will always be treated asAcqRelinside loom)
